DL Annular BOPCamerons lightweight, ram-type, low-maintenance blowout preventer
-
In the unique design of Camerons DL Annular BOP, closing pressure forces the operating piston and pusher plate upward to displace the solid elastomer donut and force the packer to close inward. As the packer closes, interlocking-steel reinforcing inserts rotate inward to form a continuous support ring of steel at the top and bottom of the packer. The inserts remain in contact with each other whether the packer is open, closed on pipe, or closed on open hole.
Other features of the DL BOP include:
Shorter height than comparable annular preventers
Available in dual configuration in certain sizes
A quick-release top with a one-piece split lock ring permits quick packer changeout with no loose parts involved. The design also provides visual indication of whether the top is locked or unlocked
Designed to simplify field maintenance, components subject to wear are field-replaceable and the entire operating system may be removed in the field for immediate changeout without removing the BOP from the stack
Twin seals separated by a vented chamber positively isolate the BOP operating system from well bore pressure. High strength polymer bearing rings prevent metal-to-metal contact and reduce wear between all moving parts of the operating systems
Manufactured to comply with NACE specification MR-01-75 for H2S service
Packers for DL BOPs have the capacity to strip pipe as well as close and seal on almost any size or shape object that will fit into the well bore. These packers will also close and seal on open hole
Also available with a three inch gas bleed port that runs from the inner diameter to the outer diameter
Stripping packers are available and reference information is available in TC1797 (CET 04-001)
Popular sizes of the DL BOP are available with high performance CAMULAR annular packing subassemblies
Camerons DL BOP is available in sizes from 7-1/16 to 21-1/4 and in working pressures from 2000 to 20,000 psi.
